Chain reaction trophy

Riding shotgun

I have tried piling vehicles together in honkers parking lot but cops come after me about the 6th or 7th vehicle i steal lol. I also tried pushing cars together with an ambulance and got a wanted level again. can someone give me a good location/advice to complete this trophy?

One of the best places is Liberty City's Times Square at a red light. You've got four lanes there, and if you time it right, there could be a lot of cars at once. Be sure it's a red light so they're not driving all over the place trying to escape.

The high way in front of the Algongiun safe house, park a limo in the way so cars pile up there and then if you think you have enough cars there plant some sticky bombs on the cars walk away and then blow the bombs, then using a ganade launcher shoot some ganades in there and you get your trophy, it worked for me
